判断线程栈爆掉的一种方法
就是TEB::StackBase-TEB::StackLimit的值约为线程栈保留大小(VC++编译器默认的是1M),就可以判断栈 爆掉了。
比如:
!teb
TEB at 01192000
ExceptionList: 0120134c
StackBase: 01300000
StackLimit: 01201000
SubSystemTib: 00000000
FiberData: 00001e00
ArbitraryUserPointer: 00000000
Self: 01192000
EnvironmentPointer: 00000000
ClientId: 00004b7c . 000059d4
RpcHandle: 00000000
Tls Storage: 1a17b928
PEB Address: 0118f000
LastErrorValue: 0
LastStatusValue: c0000034
Count Owned Locks: 0
HardErrorMode: 0
?StackBase-StackLimit=01300000-01201000=1044480B=1020K加上保护页4K,就是1024K=1M了。
又比如:
0:000> !teb
TEB at 002bf000
ExceptionList: 001cfd78
StackBase: 001d0000
StackLimit: 000d1000
SubSystemTib: 00000000
FiberData: 00001e00
ArbitraryUserPointer: 00000000
Self: 002bf000
EnvironmentPointer: 00000000
ClientId: 00002d60 . 000044e4
RpcHandle: 00000000
Tls Storage: 0069d808
PEB Address: 002bc000
LastErrorValue: 0
LastStatusValue: 0
Count Owned Locks: 0
HardErrorMode: 0
?StackBase-StackLimit==001d0000-000d1000=1020K加上保护页4K,也是1024K=1M了。
